Workplaces and buildings in Penn Street
Most of the South East has hard water, so limescale builds up on sealant, grout and fittings, and it has to be cleaned off before new sealant goes in.
Letting a property close to Amersham station? Then sealant work can be quoted for a single flat or a whole portfolio. If you look after a church, hall or community building such as Church of the Holy Trinity, its kitchen and washroom sealant needs looking after like anywhere else. For site and facilities teams at buildings such as Curzon Church of England Combined School, busy washrooms and kitchens can be resealed in phases so they stay open.

Leave it or put it right?
Guests and staff judge a building by its bathrooms. Black sealant makes a clean room look dirty, and cleaning rarely puts it right. Replacing it does. In a small place like Penn Street, homes can be exposed to wind and rain, which finds any gap, and damp in older walls is slow to dry out.
What it costs depends on the size of the job, how hard the old material is to remove and access to the work. We give a clear quote before work begins, so you know where you stand.

The process
Before we leave, we go over the finished joints with you and tell you how long to leave it. The work normally takes a few hours per area, with larger sites planned over several visits, depending on the size of the job. For a village or hamlet like Penn Street, the journey is planned in advance: tell us about narrow lanes, gates, long drives and where we can park. Everything for the job comes with us, so a second trip is avoided where possible.
- We start by looking at the rooms and agreeing what’s needed.
- Working hours are agreed, including early starts or out-of-hours work where it can be arranged.
- Each area is protected and stripped of old sealant.
- Once dry, every joint is resealed and tooled.
- We let your team know the cure time for every area.
Preparing for the visit
- Mention if the joints have been sealed before
- For business premises, tell us about site rules or sign-in
- For indoor joints, keep the area dry beforehand if you can

Advice
Quotes for commercial sealant in Penn Street
Your quote is based on your job. We take into account:
- Which sealant suits the joint
- Whether the work is at height
- The amount of work
- Mould in or behind the old joints
Leaving a failed joint generally makes the job bigger, not smaller, because water and mould keep working on it. If you are unsure, phone 0345 464 0079 or send us an email and we will give you an honest view and a quote.
Asking for a quote
A few details help us give you an accurate quote. When you ask for a quote, tell us:
- Where the property is
- Access, such as stairs, a lift or height
- Photos by email, if that is easy
- Whether it’s a home or a business
We do not publish a price list, as no two jobs are quite the same. Instead, your job gets its own clear quote. To arrange one, call 0345 464 0079 or drop us an email.
Different surfaces, different methods
Office washrooms & kitchens
A row of basins on a vanity top has a long joint that collects water. It’s cut out, cleaned and resealed in one neat line.
Welfare facilities
Staff welfare areas are needed every shift. We can plan the work in sections.
DIY versus a professional finish
A careful DIYer can reseal a simple joint, like a short, easy-to-reach joint indoors. Where it goes wrong is sealing over the old bead, working on a wet joint or overloading the gap.
Sealing over old silicone is the commonest DIY error. Silicone does not stick to old silicone, so it lifts and traps water and mould underneath. All the old material has to come out first.
Looking after it afterwards
Once the sealant has cured, a few habits help it last:
- Check extract fans are actually running
- Log resealing so you know what’s due
- Give housekeeping the cure time for every room
- Check the joints during routine room inspections
Daily cleaning with harsh chemicals shortens the life of any sealant. A mild cleaner and a soft cloth is enough for the joints.
Water from a failed shower seal can travel: through floors, into ceilings and across into corridors. Early resealing keeps it from getting that far.
Penn Street questions
Can you help a landlord with a rental near Amersham station?
Yes, landlords and agents are among the people we work for, and several properties can go on one quote. You can phone 0345 464 0079 or send us an email with the details for a clear quote.
Is Penn Street in your area for commercial sealant?
Yes. Our work covers London and the South East, and Penn Street is part of that. You can call 0345 464 0079 or send us an email and tell us what needs doing.
Do I have to be there?
We need access to the joints, so we’ll agree that with you when we book. For inside work, that normally means someone being in.
How long does the job take?
A typical job takes a morning for a small washroom, and a planned programme for bigger sites, including preparation and clearing up. Your quote will say how long we expect yours to take.
Where is Mr Mastic based?
We are a Crawley-based firm, with over 20 years’ experience. We work across South East England, London and Scotland.
Will you leave a mess?
No. We protect the surfaces around the joints, and we clear up the old sealant and our materials before we leave.
Should I try DIY first?
For a simple, easy-to-reach joint, a careful DIYer can do a reasonable job. The usual mistakes are sealing over old sealant, sealing a damp joint and using too much.
Is there any odour?
There can be a smell while the sealant cures. Opening a window helps.
For landlords and businesses
We work for landlords and agents as well as householders. Resealing between tenancies keeps a property looking cared for before the next move-in.
A neglected joint can let water reach the structure, which matters even more when someone else lives there. Resealing at the right time is simple maintenance that we can handle for you.
